A stackable cup lid includes an annular base, a lateral wall, a straw opening, a sip channel, a removable tab, a plurality of connectors, and a radial rib. The lateral wall is perimetrically connected around the annular base and delineate the general profile of the stackable cup lid. The straw opening concentrically traverses through the annular base and enables to insert a straw for cold beverage consumption. The sip channel that enables the consumption of hot beverage traverses through the annular base. The removable tab is connected to a rim of the sip channel through the plurality of connectors to open the sip channel when necessary. The radial rib is internally connected onto the lateral wall and allows the stackable cup lid to engage and secure with a rim of a beverage cup.

The present disclosure relates generally to containers and container lids. In at least one embodiment, the disclosed containers and container lids include an improved seal structure that forms a liquid-tight seal. For example, in certain embodiments, the improved seal structure is included on a built-in ring around the rim of the container. In some embodiments, the improved seal structure is included on a separate container ring for attaching to a container. In these embodiments, the contents of the container may be poured out of the container such that virtually no excess content is trapped in-between seams.

A lid for a beverage container comprising a lower lid having a perimeter skirt adapted to secure the lower lid to an opening of the beverage container, a lip portion radially inward from the skirt and extending upward from the skirt and defining an inside surface, an annular portion radially inward from the lip portion and defining a plurality of openings through which liquid from the container may flow; an upper planar lid resting on the lower lid by gravity and having a perimeter edge that is sized to closely conform with the inside surface, the upper lid covering the annular portion as it rests on the lower lid, and a stop mechanism cooperating with the lower lid and the upper lid to limit the range of motion of the upper lid with respect to the lower lid, wherein the stop mechanism enables the upper lid to move away for a distance from the lower lid in response to pressure exerted upon the upper lid by liquid flowing out of the container through the openings as the container is tilted, and wherein the stop mechanism prevents the upper lid from being expelled from the lower lid, and wherein the upper lid returns to resting on the lower lid by gravity as the container is returned to vertical.

A lid made of paper and a method for its manufacture, comprising a lid disk and a lid ring having a longitudinal axis and a circumferential wall extending in the direction of the longitudinal axis and having an inner surface and an outer surface as well as a first end and a second end. The outer circumference of the lid ring has a U-shaped region with a first wall section and a second wall section, which are connected to one another via a third wall section. The lid ring has a U-shaped region with a first wall section and a second wall section connected to each other via a third wall section. The lid ring engages with its first end in the U-shaped region of the lid disk such that the first wall section rests against the inner surface and the second wall section rests against the outer surface.

A variable volume container, comprising: a lower portion comprising a base and four walls, the four walls extending from the base and comprising a lip at the top of the walls of the lower portion; and an upper portion comprising four walls, wherein opposing walls of the upper portion comprise one or more protrusions configured to abut the lip of the lower portion to allow the upper portion to rest upon the lower portion, to place the container in an extended position; and wherein the opposing walls of the upper portion comprising the one or more protrusions are configured to flex laterally, relative to the lip of the lower portion, to allow the one or more protrusions to be disengaged from the lip to allow the upper portion to be moved downwards relative to the lower portion, to place the container in a retracted position.

A container assembly has a cup-shaped container, a lid body, a spout, a spout cover, and a spout cover securement, or lock. The lid body has a depending periphery that releasably mounts to the cup-shaped container. The lid body has a matrix extending within the periphery. The spout seat is located eccentrically and inwardly of the periphery. It has a root and a tip. The spout cover is movably mounted to the spout cover seat. When closed, the spout cover seals the spout. The lock moves between a first position and a second positon. In the first position the lock keeps the spout cover sealed to the tip. In the second position the spout cover securement permits motion of said spout cover to open. The lid is stackable on other lids. The container assembly cup comes in several forms, the different forms being mutually stacking.

A container includes a cup and a lid. The lid is adapted to mate with a brim included in the cup to close a top aperture opening into an interior liquid-storage region formed in the cup.

Lids for a container having an external peripheral rim at the upper end thereof, the lid comprising a top wall; a peripheral skirt depending downward from the top wall and having a bottom edge larger in diameter than the rim of the container and an inside surface with a locking mechanism disposed between the bottom edge and the top wall and being adapted to receive and engage the rim; and a plurality of slots defined in skirt extending upward from the bottom edge to divide the skirt into individually resiliently flexible skirt portions.

A self-drilling, self-tapping bone screw is described in which the bone screw has a drill tip free of threads and having a length at least as great as about the thickness of a proximal cortical bone layer, with the drill tip having opposed lands and a helical flute between each of the lands with each of the lands having a cutting edge configured to cut bone as the drill tip is rotated into the bone with the flutes conveying the bone debris away from the drill tip, where a lead thread begins to self-tap internal threads in the proximal cortical bone layer after the drill tip has drilled through the proximal cortical bone layer so as to avoid stripping the threads formed in the bone layer. A method of installation is also disclosed.

A lid for a beverage container comprising a lower lid having a perimeter skirt adapted to secure the lower lid to an opening of the beverage container, a lip portion radially inward from the skirt and extending upward from the skirt and defining an inside surface, an annular portion radially inward from the lip portion and defining a plurality of openings through which liquid from the container may flow; an upper planar lid resting on the lower lid by gravity and having a perimeter edge that is sized to closely conform with the inside surface, the upper lid covering the annular portion as it rests on the lower lid, and a stop mechanism cooperating with the lower lid and the upper lid to limit the range of motion of the upper lid with respect to the lower lid, wherein the stop mechanism enables the upper lid to move away for a distance from the lower lid in response to pressure exerted upon the upper lid by liquid flowing out of the container through the openings as the container is tilted, and wherein the stop mechanism prevents the upper lid from being expelled from the lower lid, and wherein the upper lid returns to resting on the lower lid by gravity as the container is returned to vertical.
